This is my Tower Arcana design. I based myself in a literal tower and in the one designed in Persona 3, Tartarus.
According to Persona 3, which uses the tarot topic to build the story:
"Portrayed as a tower stricken by lightning, from which two small figures fall down; a straight Tower of Babel allegory about pride preceding the fall. The Tower Arcana is commonly associated to overly arrogant, prejudiced and authoritarian organization, which walk to their own ironic demise. Furthermore, it is also more generically used as an omen of doom and disaster. It can be seen as the worst card of the deck, as it rarely has a positive meaning"
